Star Lord Posted October 12, 2019 Posted October 12, 2019 What is the max length I can run my first cat5e cable from my desktop computer to my 1st controller? Thanks, James
Dcroc Posted October 12, 2019 Posted October 12, 2019 Not sure if it would be any different from any other network, so I am gonna say 1000'.
TheDucks Posted October 12, 2019 Posted October 12, 2019 (edited) A properly terminated (120 Ohm) RS485 is 4000' long TOTAL. No first or last in this number. Until recent models (now have a terminate jumper) of some controllers, YOU had to make your own EOL (end of line) dangle. Rules: No 'Y" type networks (There is a LOR slow speed adapter with 2 ports, but many of us need the HS model). Only terminate ONCE (at the end). Avoid long runs against power cords (noise coupling) Edited October 12, 2019 by TheDucks
PhilMassey Posted October 12, 2019 Posted October 12, 2019 Do not mix up RS 485 (LOR) and Ethernet (LAN, WAN, WIFI). RS 485 connects via a dongle to a USB port, and Ethernet to the Ethernet port on the PC. Mixing up the two will let the magic smoke escape.
